Thanks Mudpie. Emailed Park Tool and as you said, got a answer right away.

Just in case someone else needs the info:

"The Power Spline uses a small bolt, use the CCP-2 crank puller, or the CWP-6.

The GXP uses the BBT-9 for the cups, and hex wrenches for the cranks.
They use an 8mm to intall the arms. See our repair-help area on the
website, look for bottom brackets, external type.
